Damage-control vascular surgery in Canada: supporting surgeons and teams.

SummaryIn Canada, trauma patients often present initially to non-trauma hospitals without vascular surgeons on site. Local surgeons need skills and support for damage-control vascular surgery. Canadian training programs in general surgery should equip trainees with skills in this area, including resuscitation, identification of vascular injury, hemorrhage control, and temporizing measures (e.g., shunts, ligation). Caring for trauma patients is a multidisciplinary endeavour; understanding local/regional skill sets and from whom to seek help is vital. Opportunities for skills maintenance should also be encouraged for surgeons practising at sites where acutely injured patients present.

Resuscitative endovascular balloon occlusion of the aorta in Canada: a context-specific position paper from the Canadian Collaborative for Urgent Care Surgery (CANUCS).

SummaryResuscitative endovascular balloon occlusion of the aorta (REBOA) is a well-described intervention for noncompressible torso hemorrhage. Several Canadian centres have included REBOA in their hemorrhagic shock protocols. However, REBOA has known complications and equipoise regarding its use persists. The Canadian Collaborative on Urgent Care Surgery (CANUCS) comprises surgeons who provide acute trauma care and leadership in Canada, with experience in REBOA implementation, use, education and research. Our goal is to provide evidence- and experience-based recommendations regarding institutional implementation of a REBOA program, including multidisciplinary educational programs, attention to device and care pathway logistics, and a robust quality assurance program. This will allow Canadian trauma centres to maximize patient benefits and minimize risks of this potentially life-saving technology.

Evaluation and management of the surgical abdomen.

PURPOSE OF REVIEW: The aim of this study was to describe important features of clinical examination for the surgical abdomen, relevant investigations, and acute management of common surgical problems in the critically ill. RECENT FINDINGS: Lactate remains a relatively nonspecific marker of gut ischemia. Dual energy computed tomography (DECT) scan can improve diagnosis of bowel ischemia. Further evidence supports intravenous contrast during CT scan in critically ill patients with acute kidney injury. Outcomes for acute mesenteric ischemia have failed to improve over time; however, increasing use of endovascular approaches, including catheter-directed thrombolysis, may decrease need for laparotomy in the appropriate patient. Nonocclusive mesenteric ischemia remains a challenging diagnostic and management dilemma. Acalculous cholecystitis is managed with a percutaneous cholecystostomy and is unlikely to require interval cholecystectomy. Surgeon comfort with intervention based on point-of-care ultrasound for biliary disease is variable. Mortality for toxic megacolon is decreasing. SUMMARY: Physical examination remains an integral part of the evaluation of the surgical abdomen. Interpreting laboratory investigations in context and appropriate imaging improves diagnostic ability; intravenous contrast should not be withheld for critically ill patients with acute kidney injury. Surgical intervention should not be delayed for the patient in extremis. The intensivist and surgeon should remain in close communication to optimize care.

The current state of resident trauma training: Are we losing a generation?

SUMMARY: General surgeons provide life-saving trauma care to a large portion of Canadians. Although trauma care has evolved significantly over the last few decades and now requires fewer operations, when a life-saving operation is required the expectation of competence to perform this operation has not been reduced. A recent study from the United States found decreased resident case-log volumes of trauma operations. Such findings raise the alarm of declining exposure of residents to trauma operations and beg the question of whether graduating residents are competent to care for trauma patients. Examination of the Canadian setting reveals a dearth of published information about the actual exposure of Canadian general surgery residents to trauma care. With the forthcoming evolution of general surgery education into competency-based medical education, we sound a call to action to ensure that all graduating general surgeons are able to provide the care that both the Royal College of Physicians and Surgeons of Canada and the Canadian public demand.

Multidisciplinary in-situ simulation to evaluate a rare but high-risk process at a level 1 trauma centre: the "Mega-Sim" approach

Summary: Multidisciplinary simulation has been used to successfully teach crisis resource management in operating room and emergency department settings. This article describes a "Mega-Sim" approach using an in-situ simulation that moves among multiple hospital departments to enhance multidisciplinary training and assess institutional response to a rare but high-risk event: trauma in a pregnant patient. It appears that a Mega-Sim can be used to identify systems issues, increase medical knowledge and improve perceptions of teamwork and communication within and among hospital departments.

Papillary thyroid microcarcinoma: the significance of high risk features.

BACKGROUND: Papillary carcinomas that measure 1.0cm or less are diagnosed as papillary thyroid microcarcinomas (PTMs). The clinical significance and recommendations for management of these PTMs is still evolving. The objective of the study was to compare the characteristics of small (<5mm) to large (≥ 5mm) papillary thyroid microcarcinomas. METHODS: Amongst 1459 sequential patients undergoing thyroid surgery at a single center, 132 (9%) cases were diagnosed with PTM. We performed a retrospective analysis of these cases using Fisher's Exact Test. The statistical significance was set at p < 0.05 a priori. RESULTS: A relationship between large PTM and high risk features was observed only for extra-thyroidal cancer extension (ETE). Six of 57 large PTM (11%) but none of the 75 small PTM had ETE (p < 0.01). Lymph node metastases were associated with both small PTM (5/9 cases) and large PTM (4/9 cases). A distant metastases was diagnosed in association with a small PTM. CONCLUSIONS: For PTM, neither small cancer size, nor the absence of high-risk features, excluded the possibility of synchronous lymph node metastases.

Endoscopy training in Canadian general surgery residency programs.

Currently, general surgeons provide about 50% of endoscopy services across Canada and an even greater proportion outside large urban centres. It is essential that endoscopy remain a core component of general surgery practice and a core competency of general surgery residency training. The Canadian Association of General Surgeons Residents Committee supports the position that quality endoscopy training for all Canadian general surgery residents is in the best interest of the Canadian public. However, the means by which quality endoscopy training is achieved has not been defined at a national level. Endoscopy training in Canadian general surgery residency programs requires standardization across the country and improved measurement to ensure that competency and basic credentialing requirements are met.

A comparison of outcomes including bile duct injury of subtotal cholecystectomy versus open total cholecystectomy as bailout procedures for severe cholecystitis: A multicenter real-world study.

BACKGROUND: Dense inflammation obscuring the hepatocystic anatomy can hinder the ability to perform a safe standard laparoscopic cholecystectomy in severe cholecystitis, requiring use of a bailout procedure. We compared clinical outcomes of laparoscopic and open subtotal cholecystectomy against the traditional standard of open total cholecystectomy to identify the optimal bailout strategy for the difficult gallbladder. METHODS: A multicenter, multinational retrospective cohort study of patients who underwent bailout procedures for severe cholecystitis. Procedures were compared using one-way analysis of variance/Kruskal-Wallis tests and χ2 tests with multiple pairwise comparisons, maintaining a family-wise error rate at 0.05. Multiple multivariate linear/logistical regression models were created. RESULTS: In 11 centers, 727 bailout procedures were conducted: 317 laparoscopic subtotal cholecystectomies, 172 open subtotal cholecystectomies, and 238 open cholecystectomies. Baseline characteristics were similar among subgroups. Bile leak was common in laparoscopic and open fenestrating subtotal cholecystectomies, with increased intraoperative drain placements and postoperative endoscopic retrograde cholangiopancreatography(P < .05). In contrast, intraoperative bleeding (odds ratio = 3.71 [1.9, 7.22]), surgical site infection (odds ratio = 2.41 [1.09, 5.3]), intensive care unit admission (odds ratio = 2.65 [1.51, 4.63]), and length of stay (Δ = 2 days, P < .001) were higher in open procedures. Reoperation rates were higher for open reconstituting subtotal cholecystectomies (odds ratio = 3.43 [1.03, 11.44]) than other subtypes. The overall rate of bile duct injury was 1.1% and was not statistically different between groups. Laparoscopic subtotal cholecystectomy had a bile duct injury rate of 0.63%. CONCLUSION: Laparoscopic subtotal cholecystectomy is a feasible surgical bailout procedure in cases of severe cholecystitis where standard laparoscopic cholecystectomy may carry undue risk of bile duct injury. Open cholecystectomy remains a reasonable option.

A gap analysis of the potential use of resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma at two major Canadian trauma centers.

OBJECTIVE: Uncontrolled hemorrhage poses significant morbidity and mortality among injured patients. Resuscitative endovascular balloon occlusion of the aorta (REBOA) utilizes a rapidly-administered minimally invasive transfemoral balloon catheter that is inflated for aortic occlusion, allowing for time to arrange definitive surgical or angiographic intervention. As indications for its use continue to evolve, this study sought to evaluate whether there is a potential need for REBOA implementation in two high-volume trauma centers in Edmonton. METHODS: Patient data within our provincial trauma registry was reviewed between 2015 and 2017 to identify major trauma patients (Injury Severity Score ≥ 12). Patients eligible for REBOA included patients with blunt or penetrating trauma to the torso or pelvis, AND death prior to discharge; and patients taken to the operating room or interventional radiology suite within 4 h of arrival. Charts were reviewed to determine if patients met current conventional criteria for REBOA. RESULTS: Out of 3415 trauma patients during our study period, 237 patients met the registry screen as potentially eligible for REBOA. After primary researcher review, 67 patients underwent full chart review and then 2 trauma surgeons determined that 38 (1.1% of the study population) met criteria for deploying REBOA. CONCLUSION: A small but significant number of trauma patients at the two trauma centers were identified as potential candidates for REBOA use. Implementation of a REBOA program should be done in alignment with existing clinical practice guidelines and professional society recommendations.

RéSUMé: OBJECTIF: L'hémorragie incontrôlée entraîne une morbidité et une mortalité importantes chez les patients blessés. Le clampage aortique par sonde d'occlusion aortique endovasculaire (resuscitative endovascular balloon occlusion of the aorta [REBOA]) utilise un cathéter à ballonnet transfémoral mini-invasif à administration rapide qui est gonflé pour l'occlusion aortique, ce qui laisse le temps d'organiser une intervention chirurgicale ou angiographique définitive. Alors que les indications de son utilisation continuent d'évoluer, cette étude a cherché à évaluer s'il y avait un besoin potentiel de mise en œuvre de REBOA dans deux centres de traumatologie à haut volume à Edmonton. MéTHODES: Les données sur les patients dans notre registre provincial des traumatismes ont été examinées entre 2015 et 2017 afin d'identifier les patients traumatisés majeurs (Score de gravité des blessures ≥ 12). Les patients éligibles au REBOA comprenaient des patients présentant un traumatisme contondant ou pénétrant au torse ou au bassin, ET le décès avant la sortie; et les patients conduits à la salle d'opération ou à la salle de radiologie interventionnelle dans les 4 heures suivant leur arrivée. Les graphiques ont été examinés pour déterminer si les patients répondaient aux critères conventionnels actuels de REBOA. RéSULTATS: Sur les 3 415 patients traumatisés pendant notre période d'étude, 237 patients ont répondu à l'examen du registre comme étant potentiellement éligibles pour le REBOA. Après examen par le chercheur principal, soixante-sept patients ont été soumis à un examen complet de leur dossier, puis deux chirurgiens traumatologues ont déterminé que 38 (1,1 % de la population étudiée) répondaient aux critères de déploiement de la REBOA. CONCLUSION: Un nombre restreint mais significatif de patients traumatisés dans les deux centres de traumatologie a été identifié comme des candidats potentiels à l'utilisation de REBOA. La mise en œuvre d'un programme REBOA doit se faire en conformité avec les directives de pratique clinique existantes et les recommandations de la société professionnelle.

Data capture and communication during transfers to definitive care in an inclusive trauma system.

INTRODUCTION: Background trauma survivors in rural areas transferred to urban centers have higher mortality than trauma patients admitted directly to urban centers. Transfer data in trauma registries is important for injury control. Prehospital and early physiologic data may reflect processes of pre-hospital care. British Columbia currently has no standardized process for trauma patient data transfer. PATIENTS AND METHODS: We performed a retrospective data analysis for major trauma patients (ISS>15) transferred to a Level I trauma center over a 1year period (n=243). Completion rates of paramedic form and ATLS primary survey variables were extracted. Nominal and interval descriptives were calculated. Documentation rates were considered deficient at <80% and severely deficient <60%. Odds ratios were calculated for primary facility data based on ISS ≥30 vs ISS <30, with 2-sided p-values for confidence intervals RESULTS: Two hundred forty-three patients met inclusion criteria with a mean ISS of 26. Most injured patients were male (79%), the predominant mechanism was blunt (93%) and the average age at injury was 51 years old. Two hundred eighteen patients arrived by Emergency Health Services, and 140 (64%) of EHS pre-hospital forms were transferred with the patient chart. Pre-hospital airway, physiologic data, and GCS completion rates were severely deficient (43-49%). Primary facility data was adequately completed for airway management, systolic blood pressure, and heart rate in (80-83%). Completion rates were deficient for respiratory rate, GCS and temperature (60-77%). An ISS score ≥30 was significantly associated with a lower completion rate for GCS. DISCUSSION AND CONCLUSION: Overall, documentation for inter-hospital transfer of major trauma patients in BC has significant deficiencies. Physiologic and basic ATLS variables are often omitted in transferred charts. The potential for adverse events is high but performance improvement is achievable. We recommend education, training and a standardized trauma transfer protocol to improve system-wide information transfer.

Video gaming promotes concussion knowledge acquisition in youth hockey players.

While the positive uses for video games in an educational setting have also been established, the educational aim is usually made explicit. The goal of this research was to develop a video game wherein the educational aspect was implicitly embedded in the video game, such that the gaming activity remained interesting and relevant. Following a pilot study to confirm the usability of an in-house developed game, two studies were conducted with 11-17 year old hockey players (N(1)=130, N(2)=39). Results demonstrated that participants playing the experimental version of the video game scored significantly higher on a concussion symptoms questionnaire, in a significantly faster time, than participants playing the control version of the game. Most participants indicated that they enjoyed the game and would play it again. These results suggest that educational material can be conveyed successfully and in an appealing manner via video game play.
